FIRE-HOSE.

SPECIFICATION forming part of Letters Patent No. 658,586, datedSeptember 25, 1900 Application filed August 17, 1899- Renewed July 27,1900- Serial No. 25,048. (No model.)

To all whom, it ntcty concern.-

Be it known that I, MEINHARD REILING, a citizen of the United States,residing at Fort Wayne, in the county of Allen and State of Indiana,have invented new and useful Improvements in Variable or DifferentialNozzles for Fire-Hose, of which the following is a specification.

My invention relates to variable or differential nozzles for fire-hose,my purpose being to provide a simple and economical construction bywhich the diameter of the exit-opening may be regulated, the size of thestream issuing from the nozzle being thereby diminished and its velocityand range correspondingly increased.

lt frequently happens at fires that intense heat or other circumstancesrender it necessary or desirable that the fireman handling the nozzleshould stand temporarily at such a distance from the flames that astream delivered by the nozzle at the maximum capacity of the latterwill fail to reach the point where its effect is needed.

It is my object, therefore, to provide simple and easily-operated meanswhereby the diameter of the exit-opening may be reduced WllhOllLshutting off the delivery of water or arresting the action of theengine.

My invention consists, to these ends, in the novel features ofconstruction and new combinations of parts, which will now be describedin detail, and then particularly pointed out and defined in the claimsthat terminate this specification.

For the purposes of the following description reference is had to theaccompanying drawings, in Which Figure 1 is a central longitudinalsection of a nozzle having my invention, the parts being shown in theposition they occupy when the stream delivered is of maxim um diameter.Fig. 2 is a similar sectional View showing the same parts adjusted tothe position for delivering astream of minimum diameter. Fig. 3 is atransvers section, the scale being somewhat enlarged. I

The reference-numeral 1 in said drawings indicates a nozzle forafire-hose having an exit end 2, which is tapered or shaped approximatelylike a truncated cone, the inte- 'inner surface of the tubular section2.

rior passage having a slight contraction, as is usual in these nozzles.

Within the nozze l I arrange a short tubular section 2*, whichissupported concentrically by longitudinal ribs 3, which may be formedeither upon the inner face of the nozzle 1 or upon the out-er surface ofthe tubular section 2, so that the latter may be capable of anadjustment in the direction of its axis which coincides with the axis ofthe nozzle. Its end is tapered or contracted slightly, the angle beingless than that of the nozzle, its outside diameter being such that whenpushed to its outward limit of movement its contracted end Willaccurately fit the exit end of the nozzle, as shown in Fig. 2, therebyreducing the interior diameter of the latter to the dimensions of thetubular section. To effect a still further reduction, a secondtube-section 4, of greater length than the part- 2. is arrangedconcentrically within the nozzle, lying partly Within the latter andpartly within the tubular section 2 the contraction of its exit endbeing less than that of the latter. This part is supported, like theother, upon ribs 5, and, if necessary, auxiliary supporting-ribs may beprovided between the outer face of the part 4 and the Longitudinalmovement is imparted to the tubesections by small spur-gears 6, whichmesh with toothed racks 7 on the said sections.

The gears 6 are mounted on short spindles 8, passing through the nozzleat suitable points and provided with handles 9, by which they areoperated. 'lhese handles are preferably connected to the outer ends ofthe spindles by a pivotal joint, which enables them to be turned so thatthey lie against the exterior of the nozzle,where they are not liable tocatch in the clothing or become injured by an accidental blow. Thesecond tube-section 4 when pushed forward fits at its exit end closelyWithin the corresponding end of the first section and reduces thediameter of the opening through which the water must pass to theinterior diameter of its own exit end. It is evident that thesesuccessive reductions may be varied as desired by merely varying thedimensions of the tubesections.

I do not limit my invention to the use of any specific number of thesetube-sections, as I may employ one only, or I may use any number greaterthan one.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is

1. A nozzle for fire-hose, having a tapering unobstructed exit end, anopen inlet end arranged in alinement, an interior tube-section providedwith a tapering exit and an open inlet alined with the exit and inlet ofthe nozzle-body, and means for shifting the tubesection to move itstapering exit end into the exit of the nozzle-body, substantially asdescribed.

2. A nozzle for fire-hoze, consisting of a nozzle-body having anunobstructed exit at its front end, an open inlet at its rear end alinedwith said exit, an interior tube-section having a front exit end and arear inlet end in alinement with the said exit and inlet of thenozzle-body, and mechanism having a part thereof extending laterallythrough the side wall of the nozzle-body for shifting said tube-sectionlongitudinally to move its exit end into orout of the exit of thenozzle-body, substantially as described.

3. A nozzle for fire-hose, consisting of a nozzle-.body, having an exitand an inlet end, an interior tube-section having an exit and an inletend alined with the inlet and exit ends of the nozzle-body, a racksecured to and extending longitudinally of the outer surface of thetube-section, a gear arranged between said tube-section and thenozzle-body, and means for rotating said gear to shift the tubesectionlongitudinally and place its exit end within the exit of thenozzle-body, substantially as described.

4. A nozzle for a fire-hose, having a tubesection arranged therein, arack secured to and extending longitudinally of the tubesection, a gearengaging said rack, and means for rotating the gear to shift thetube-section longitudinally and move its front end into or out of theexit of the nozzle, substantially as described.

5. A nozzle for a fire-hose, consisting of a nozzle-body having alateral orifice, an interior tube-section, a rack securedto andextending longitudinally of the tube-section, a gear arranged betweensaid tube-section and said nozzle-body, and a spindle extending throughthe lateral orifice in the nozzle-body and connected with said gear toshift the tube-section and move its exit end into or out of the exit ofthe nozzle-body, substantially as described.

6. The combination with a nozzle for firehose, of a plurality ofinterior, concentric tube-sections having support upon longitudinalribs, and means for independently adjusting said sectionslongitudinally, substantially as described.

7. The combination with a nozzle for firehose, of one or moreinterior,concentri0, tubesections supported upon longitudinal ribs, aspur-gear meshing with a rack on each section, and a short spindlepassing through the wall of the nozzle to carry said gear, substantiallyas described.

8. The combination with a nozzle for firehose, of one or more interior,concentric tube- Y sections supported by longitudinal ribs, a spur-gearmeshing with a rack on each section, a short spindle passing through thewall of the nozzle to carry said gear, and a handle connected to theouterend of the spindle bya pivot, substantially as described.

9. The combination with a nozzle for firehose, of a plurality ofinterior, concentric tube-sections of successively-reduced diametersupported upon longitudinal ribs, said sections being of differentlength, spur-gears meshed with racks on said tube-sections and carriedby spindles passing through the wall of the nozzle, and handles pivotedto the outer ends of said spindles, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing wit- DGSSGS.
